Once I catch my breath and look back at one of our popular INE courses like the CCNA Wireless course, I can delve a bit deeper into certain subjects that we did not have time for in the course. This is one of those moments. Let us get more detailed about Cisco’s implementation of Radio Resource Management (RRM) in the Cisco Unified Wireless Network architecture.

Radio Resource Mangement

In today’s wireless LAN infrastructures, of course users want more and more bandwidth in a greater and greater coverage area. This is tricky to implement, however, since adding more and more powerful access points can actually do more harm than good for throughput. The goal of Cisco’s Radio Resource Management is to act like a Radio Frequency engineer built-in to the equipment. RRM allows the Cisco Unified Wireless equipment to continuously monitor the Radio Frequency environment and adjust things like channel assignments and and power levels to ensure optimal coverage and throughput. The exciting goal here is to make the wireless infrastructure “self-healing”.
